I’m creating a procedural cross-lap script that converts any surface into a series of ribs that can be laser cut. I have pairs of planes that intersect with these ribs. I then find the intersections, resulting in pairs of lines. I pull out the end points of these lines. As you can see, they are in tight pairs. I need to index out the line in each pair that is higher up, as its endpoint will be used to construct a rectangle that cuts through the rib, resulting notches for cross-lapping. To do this, I’ve extracted the xyz of each endpoint, and am now trying to figure out how to index the points with the greatest z value for each pair. I’ve tried using the Maximum component but it does not return the index of the item, so I can’t generate a list of indexes to filter out the lines corresponding the higher endpoint

you could do something like this, where each couple of Curves are inserted in a different branches with grafted Merge, then extract their end-point z-coordinate and sort those (in ascending order)
Curves are sorted simultaneously:

then, if you want to pick only the Curves for which the end point coordinate is lower, you can just List item (first item is always the smaller)
a note, you can zoom-in the Sort component and add more simultaneously-sorted inputs if needed:
